Mindspeed Technologies Inc. is simultaneously introducing a seventh generation of its Comcerto VoIP processor and a software suite that includes protocols for 3GPP and IP Multimedia Subsystems. The Comcerto 900 M82910 integrates 18 processors, including DSP banks, an ARM-based packet-processing engine, and dedicated co-processors for echo cancellation and video processing.

Michael Metzger, executive director of marketing for Mindspeed's processor families, said that the 375MHz Countach DSP cores are linked by a 51Gbps nonblocking bus, which also links two 450MHz ARM1136 cores used for packet processing. Each DSP block also has a 375MHz ECAN coprocessor, a design originally used for echo cancellation but applied to video processing as well.

Metzger said the core application of the processor will be in heavy-aggregation IP Multimedia Subsystem gateways used in fixed-mobile convergence networks. Other applications include Class 4 and 5 switches, mobile switching centers, radio network controllers and access gateways.

Thanks to Mindspeed's legacy in asynchronous transfer mode, the Comcerto architecture is built for voice-over-ATM as well as VoIP. The M82910 can handle more than 672 channels of VoIP traffic and, in a wireless network, more than 200 channels of adaptive multirate traffic in W-CDMA. The architecture is designed to mix and match codecs in a single aggregator.

The Comcerto software suite, meanwhile, includes all the defined protocols for 3GPP, including the Iu and NbUP protocols in a state-machine implementation, carried over both IP and ATM. For 2G+ services, the software supports tandem-free operation and circuit-switched data.

The software, applicable for all Comcerto processors, is offered in both CDMA (SWO-002-CDMA) and W-CDMA (SWO-003-W-CDMA) versions at a one-time licensing fee of $75,000 each. The M82910, which dissipates 2.7W, is now sampling, with fourth-quarter production slated. It is packaged in 19mm BGA, priced at $250 each in quantities of 10,000.
